With the words “for the Lord’s sake” Peter is reminding his readers that their actions affect the Lord’s reputation. God created people for the glory of his own great name, and then redeemed his chosen for the same purpose. People in the community know who is a Christian, and inevitably link these people to God so that their conduct reflects on their estimation of who God is. Abram knew himself to be a “sojourner and foreigner” in the land of Canaan (Genesis 23:4). When he returned from his victory over the kings that carried away the people and possessions of Sodom and Gomorrah, he declined to take his share of the spoil, but instead willingly returned them to the king of Sodom. His reason for doing so was God’s reputation in the eyes of the locals (Genesis 14:21–24).
